"Were there attempts to reach the mountain?"
Translation:Ĉu estis provoj atingi la monton?
kion vi ne komprenas?
ĉu - marks a question
estis - past tense "it was, there were"
provoj - from the verb "provi", to try; as a noun, "the action of one who tries" ; so "tries" or "attempts"
atingi - "to achieve" or "to reach"
la monton - "the mountain"; in the accusative; the object of "atingi"
unless you don't understand why there was any trouble reaching the mountain, which I'm a little fuzzy on; I mean, mountains are right there, and you just need to walk or drive or something to get to them. climbing them, that can be the tricky bit,
